Answer: it is x=5/7 or x=-5/7
X^2 - 10x + 36 = 0;
We use the quadratic formula: x = ( - b + or - i

)/ (2a);
We have a = 1; b = -10; c = 36;
Then, x = ( 10 + or -i

)/2 = 5 + or -

)/2 ;
Answer: 3 hours
Step-by-step explanation:
the answer this can be solved by the function:
324 = 27x + 243

27x = 81
/27 /27
x = 3 hours past 7.
Answer:
The ratio is 29:30
Step-by-step explanation:
First, we need to calculate the mass of sugar in the mix
That would be 100-41-29 = 100-70 = 30g
So the ratio of blackberry to sugar would be mass of the blackberry : mass of sugar
From the question, mass of blackberry = 29g while the mass of sugar = 30g
Mass of blackberry to mass of sugar = 29:30
